FEV to show compressed natural gas light-duty concept engine with ATAC combustion system at 2011 SAE World Congress

Green Car Congress

FEV) a leading developer of advanced powertrain and vehicle technologies, will exhibit a lean burn engine concept at the SAE 2011 World Congress that has been modified to run on Compressed Natural Gas (CNG). FEV developed ATAC more than a decade ago, targeting large-bore engines in stationary and heavy-duty applications.

Experts view on future transportation fuels

Green Car Congress

Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. In the pneumatic hybridization scheme, each cylinder is connected via a fully variable charge valve to a shared pressure tank. Dönitz et al. Source: ETH Zürich.

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve.
